| Abstract: | In this paper a new mechanical model was established to study the work equipment of a loader. The lifting structure was analyzed in details and a new method for finite element treatment was proposed. Based on them, a whole mechanical model was built up after some parts of work equipment were simplified or ignored. The stress of work equipment was analyzed using the finite element analysis system. Comparing the results from the finite element analysis and experiment, as well as the result from the formula in two typical cases, the rationalities of this model and the dealing method were testified. At last the maximum stress sections on work arms were found out in several cases, which provided a basis for modifying designs in the future. |
